H A D | Makefile | 95a38f34 Wed Apr 01 19:35:00 CDT 2009 H. Peter Anvin <hpa@linux.intel.com> x86, setup: compile with -DDISABLE_BRANCH_PROFILING
Impact: code size reduction (possibly critical)
The x86 boot and decompression code has no use of the branch profiling constructs, so disable them. This would bloat the setup code by as much as 14K, eating up a fairly large chunk of the 32K area we are guaranteed to have.
